(Solved): Protein Folding Is Critical For Proper Function. Which Statement About Protein Folding Is NOT True? ...


  1. Protein folding is critical for proper function. Which statement about protein folding is NOT true?
  1. Glycosylation state can indicate how long a protein has failed to find the proper conformation.
  2. Chaperones prevent protein aggregation into large complexes.
  3. Some proteins can spontaneously fold into correct structures.
  4. Unmasked hydrphobic domains are a marker of misfolding.
  5. Misfolded proteins are targeted to be exocytosed out of the cell to prevent accumulation.
  1. Which pathway of unfolded protein response involves a noncanonical cytoplasmic splicing process?
  1. Both IRE1 and PERK
  2. ATF6
  3. IRE1
  4. PERK
  5. All three pathways

  1. The 19S cap domains on the proteosome:
  1. remove carbohydrate groups from the protein.
  2. remove both carbohydrates and ubiquitin from the protein.
  3. add ubiquitin to the protein.
  4. hydrolyze ATP to linearize the protein and pull it into the proteolytic pore.
  5. add carbohydrate groups to the protein.
  1. Where does ubiquitylation of misfolded ER protein occur?
  1. In the Golgi apparatus
  2. The cytosolic side of the ER membrane
  3. The lumenal side of the ER membrane
  4. The extracellular side of the plasma membrane(1) Protein folding is critical for proper function. Which statement about protein folding is NOT true? A. Glycosylation stat
